Plant and animal DNA suggests first Americans took the coastal route

  > Discovering sites along these routes won’t be easy, because most are now likely to be underwater. But this summer, Davis and his colleagues began surveying areas of the Pacific Ocean... It's surprising this was just given two or three sentences, because this is kind of a crux of the argument. If people had done a coastal migration that long ago, they'd be doing it when sea levels were significantly lower, meaning a lot of the evidence is gone at this point. (Something inside me hopes they find something, though.)
